Breast point cloud segmentation method and device, storage medium and computer device

Abstract

The invention discloses a breast point cloud segmentation method. The method comprises the steps of obtaining three-dimensional point cloud data; deleting the point cloud corresponding to the bed plane area from the three-dimensional point cloud data according to a preset condition to obtain a chest area point cloud; determining an upper segmentation boundary and a central segmentation boundary ofthe chest through offline calibration; upwards constructing a horizontal tangent plane according to a preset height increasing value until the point cloud on the horizontal tangent plane meets a boundary segmentation condition, and fitting the point cloud on the current horizontal tangent plane into an axilla segmentation boundary; constructing a chest lower side segmentation boundary according to the chest upper side segmentation boundary; and extracting a chest scanning area point cloud. According to the technical scheme, the point cloud of the breast area can be quickly and accurately segmented to obtain the three-dimensional space information of the breast area, so that a basis is provided for subsequent scanning trajectory planning.

Description

technical field [0001] The present invention relates to the technical field of point cloud data processing, in particular to a breast point cloud segmentation method, device, storage medium and computing equipment. Background technique [0002] Ultrasound examination, a non-surgical diagnostic examination, is painless, non-invasive, and non-radioactive to the subject. Moreover, ultrasound can clearly display various cross-sectional images of internal organs and their surroundings. Since the images are full of solidity and close to the real anatomical structure, the application of ultrasound examination can make an early diagnosis. Based on the many advantages of ultrasonography, from professional medical disease diagnosis to daily health indicator assessment, its application range is becoming wider and wider. [0003] With the development of medical diagnostic technology and the improvement of economic level, more and more women begin to pay attention to breast health, and ...
